Even though this is a bar soap i'm reviewing it as a shampoo. As a body soap, it worked great for my skin (and even though i don't have back acne, it didn't cause anything and prevented it from further occurring cause it does happen when i use soaps with mineral oil). My skin DID feel a little tight after, meaning i definitely think its drying so for body i would want a more moisturizing soap but after i put on a little bit of lotion on my body i can't really tell the differnece. It works great on my face too.... but i''m not sure if it's leaving residue behind or not.... NOW, for the hair. I really wanted to try a shampoo bar but can't find any natural ones around my area, and was very confused (and i don't like ordering form online). So, when i was shopping at bulk barn, i came across their bar soaps for body and thought, why not try it on the hair since the ingredients are similar and natural. First, you should try it on you rhair only after you've clarified your hair using whatever you use, (baking soda, vinegar, or a clarifying shampoo). I used head and shoulders because it's super drying and i hate it but it really strips everything from my hair. Then, I used this (REALLY LATHERS ALOT :D) with a vinegar rinse after (i'm sill having trouble figuring out proportions). The result was very soft hair. I think it does leave behind residue (especially if you don't use a viengar rinse) but i'm tying to figure out a way to fix that. hopefully i'll figure out a way because i luv the way it makes my hair feel and how manageable my hair becomes
